1. What is Feet to PSI Conversion?

Definition: This calculator converts a height of water column in feet to pressure in pounds per square inch (PSI).

Purpose: It's commonly used in hydraulics, plumbing, and engineering to determine water pressure based on elevation head.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Pressure in pounds per square inch (PSI)
• \( h \) — Height of water column in feet (ft)
• 2.31 — Conversion factor (1 PSI = 2.31 feet of water head)

Explanation: The height in feet is divided by 2.31 to convert to PSI, since 1 PSI equals the pressure exerted by a 2.31-foot column of water.

3. Importance of Feet to PSI Conversion

Details: Understanding this conversion helps in designing water systems, calculating pump requirements, and ensuring proper pressure in plumbing systems.

4. Using the Calculator

Tips: Simply enter the height of water column in feet. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 2.31?
A: It comes from the specific weight of water (0.433 psi/ft) - 1/0.433 ≈ 2.31 ft/psi.

Q2: Does this work for other liquids?
A: No, this is specific to water. Other liquids would require adjustment based on their specific gravity.

Q3: Is temperature a factor in this conversion?
A: The 2.31 factor assumes water at standard conditions (60°F). For very precise calculations at different temperatures, adjustments may be needed.

Q4: How accurate is this conversion?
A: For most practical purposes, it's sufficiently accurate. The exact value is 2.30666 ft/psi, but 2.31 is the standard approximation.

Q5: Can I use this for water towers or tall buildings?
A: Yes, this is commonly used to calculate static pressure in tall water columns like water towers or high-rise plumbing systems.
